How do you folks clean-up root partition, I have too much junk in there.
df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda3        74G   61G  9.3G  87% /

I've already removed all the files from:
/usr/portage/distfiles

So that's a Microsoft answer: 100% completely technically correct, and
nonetheless still tells you absolutely nothing.

But it's the best answer I can give you until you read this:

'du' is your friend : it has lots of options, so read the 'man'.
that will tell you what's using so much space, then you can delete stuff.
My system shows :

Thanks.
Yes, I used:
du -a /var | sort -n -r | head -n 10

and found my /var/log/messages was over 5Gb

Junk can accumulate in hundreds of places, it all depends how you set
the host up. These are often culprits:

/home/*
/tmp/
/var/tmp/portage
/usr/src

I highly recommend sys-fs/ncdu, an ncurses front end to du. Definitely
much better than piping du output through sort. You can even directly
delete folders/files when you see that something is taking up more space
than expected.

You can maintain that with "eclean-dist -d". Also check portage/packages 
for old binary packages.

ncdu also makes it easier to find where the space is consumed. "ncdu /" 
will scan and sort by size.

Sorry, should have been:

   ncdu -x /

This will exclude mounted filesystems.

A good place to start is to make a hotlist of anything that isn't owned by
a package.

You really shouldn't randomly delete things that portage thinks belongs to
someone.

But if you find orphaned junk, it could be fair game.  If you have
something bulky that DOES belong to a package, consider using emerge
--unmerge on it if you don't need it.

You can build a list of orphaned files with qfile

qfile -o $(find / -xdev -type f)

You may want to exclude /etc/ from the search path as that produces a lot
of hits.

I get a few hits on this, so far.  If it reports that it is a orphan,
just how sure is it that it is?  Is it 100% and safe to delete or 90%
and could break something?

As with everything Gentoo, it is 100% safe to look at the output and
make your own decisions. Generally, if its in /lib or /usr/lib it's
usually fair game, but not if it's in /etc.

Take backups (including the full path and permissions)

And make sure you have a working boot disk/cd/usb/... to restore any files you deleted.

I have some in lib directories.  I skipped the ones in /etc and home
directories.  This is a example:

/lib64/firmware/liquidio/lio_410nv_nic.bin

That is just a small snippet.  There are so many, it seems odd that that
many would be left behind but equery shows they belong to nothing for
the ones I tested on. 

Thought it better to ask first.  ;-)  May just leave it alone.

How did they get there? Did you manually install some firmware or
drivers? To be safe, run qfile on each of them, they may be recorded as
having been installed to /lib instead of /lib64 or vice-versa. If you
think they are no longer needed, move them elsewhere, reboot and see what
breaks.

You should rarely delete anything in /lib/modules. These files are
created during the kernel build/install process.

If disk space is not critical, that is the easiest option.

I have no idea but I can assure you, it was not me.  ;-)

That's what I thought.  I knew they were put somewhere but wasn't 100%
